Title: Recording/reproducing method and apparatus, processing apparatus, and recording medium for video signal having copy control information
Inventor: KIMURA HIROYUKI
IPC: G11B20/00
Filed: 1998-09-15
Abstract: Electronic watermark information obtained by changing a luminance value of a luminance signal in a video signal and a copy generation management signal (CGMS signal) inserted into an area out of a scan region of the video signal are recorded into a recording medium.  A reproducing apparatus comprises an electronic watermark information detecting circuit, a CGMS signal detecting circuit; a control circuit to which detected electronic watermark information and CGMS signal are supplied, and a video signal processing circuit controlled by an output of the control circuit.  When the electronic watermark information and the CGMS signal have a rational relation, the video signal processing circuit is controlled to output the video signal.

Title: A package assembly for keeping, storing, displaying and handling disc-shaped products
Inventor: LINDBLOM GOERAN
IPC: G11B33/04
Filed: 1997-03-21
Abstract: A package assembly for keeping, storing, displaying and handling disc-shaped products, such as compact discs and the like, wherein the assembly is comprised of a sleeve or pocket that is produced by folding and/or gluing a first paperboard or cardboard-like blank, and a slide or tray which is intended to removably receive at least one disc-shaped product and which is produced by folding and/or gluing a second paperboard or cardboard-like blank, wherein the sleeve has an opening through which the product-carrying slide can be inserted and withdrawn, wherein the slide includes product-constraining means, and wherein the sleeve and the slide include mutually coacting means which function to maximize the extent to which the slide can be withdrawn from the sleeve for the removal and insertion of a product into the space intended therefor.       According to the invention, a folded part (74, 76) of the slide (70) in the region of its bottom part functions both as a part of a product-receiving pocket (26) and as a partition wall (74) that enables two products to be received in mutually parallel and mutually separated relationship, wherein the folded part includes a separate foldable flap (76) that forms a bottom abutment (76', 76") for products received on respective sides of the partition wall (74), wherein the bottom abutment of said flap (76) also functions to restrict the extend to which the slide can be withdrawn from the sleeve (80').

Inventor: HALL JOHN E JR
IPC: F24D17/00
Filed: 1997-04-12
Abstract: A water saving device (18) for use with domestic hot water systems of the noncirculating storage tank heater type uses a hydraulic motor do drive a water pump (48) to pump water from the hot water pipe (21) to a cold water pipe (22). Pumping begins when a hot water tap connected to the device (18) is turned on and the water in the hot water pipe (21) is cold. Pumping continues until a temperature sensing element (70) senses the hot water has reached the water saving device (18) and actuates a valve (65). When hot water is present at the device (18), the valve (65) permits the hot water to pass directly to the tap instead of driving the hydraulic motor (47).

Abstract: A paper calender has a stack of rolls arranged one above the other. They form an upper stack and a lower stack with a common center roll. Additional center rolls are carried on levers that are capable of pivoting about axes fixed with respect to the frame, and are capable of being placed under load by devices applying force. These devices should be designed to be powerful enough to be capable of compensating for more than the total weight of the associated roll and the parts connected to it. As a result of the various possible settings for the line load, the finishing of the paper can be improved. A method is provided for operating a paper calender having an upper stack of rolls and a lower stack of rolls positioned below the upper stack. Each stack is individually capable of being placed under load by upper and lower force generators. The calender also includes a common center roll that is supported on a frame, and remaining center rolls carried on levers capable of pivoting about axes fixed with respect to the frame. The levers are capable of being placed under load by force applying devices to compensate for more than the total weight of the respective roll and the parts connected to it. The method includes exerting farce on the upper stack independently of the force exerted on the lower stack, exerting force on each lever independently of the force exerted by the other force applying devices, and setting the load characteristic curves in the upper stack and lower stack differently.

Abstract: An electronic article security system (10) monitors articles (12) sold by a retail store (16) to detect shrinkage. The articles (12) are tagged with RF-ID  security tags (22). Each security tag (22) has a unique or semi-unique serial number for identifying individual products. Transaction records (36) generated from point-of-sale terminals in the store are sent to a remote computer (38).  An interrogator (42) and surveillance camera (58) are positioned near the store exit. When an article (12) having the RF-ID security tag (22) is detected as passing through the store exit, the interrogator outputs a signal derived from the security tag (22). The output signal includes the security tag serial number. Also, the camera (58) takes an image of the person moving the tagged article through the exit. The interrogator output signal is sent to the remote computer (38). The remote computer (38) periodically compares the transaction records (36) with the interrogator output signals to detect any discrepancies therebetween. The discrepancies are investigated by viewing the captured video images near the time of the discrepancies.

Abstract: A modem parameter required for a modem apparatus is stored in a memory for each telephone number of a communication destination in advance based on past communications. At a communication time, a receiver side is notified of an execution of the short protocol by a QTSD signal, and sequentially a QINFO signal that includes the modem parameter is transmitted.      Since the modem parameter is received by the communication destination, the pre-protocols such as exchange of parameter, etc., are shortened so that communication time can be shortened. Moreover, since the transmission of modem parameter is repeated until it is confirmed that the communication destination receives the modem parameter, occurrence of communication errors can be avoided so that the shortened pre-protocols can be surely executed.
